Yes and no
I wrote a book once, and as part of the book I had to do quite a bit of research into the Qur'an, the Hadiths, and the Sunna. I am a strong Christian, and while I cannot claim to have even the level of knowledge of Islam that the normal Muslim layman has, I can say that it was a real education to see for myself how so many Muslims have been led astray from the teachings in the Qur'an. As far as I can tell, most of the problem lay in the Hadiths and Sunnas - the writings and sayings of Muslim scholars after the death of Muhammed. The prophet Muhammed stated that nothing is to be written of him or the teachings in the Qur'an after his death, but that is precisely what the Hadiths and Sunnas are. For instance, it was in one the Hadiths by "Bukhari" (again, if I remember correctly) that says if a woman or a black dog walks in front of a man praying to God, then God will not hear his prayers. That is not in the Qur'an, but there are those who claim to be Muslim who follow that Hadith.
So I compare those who follow the Hadiths and Sunnas to the point where such corrupts their faith to those who claim to be Christian, who follow verses in Deuteronomy to justify acts that Jesus Himself obviously rejected.

I don't understand the pathological hatred some people have for Islam. Is it the cultural rivalry that Europe had with the Middle East for so long? Can't you realize that your religions and the worldviews they promote are almost identical? You only spend a moment trying to deny the violence in India, but we can chalk that up to just plain old ignorance. It's sad that you aren't any better than they are. I wish you were. But the facts show that, in a country where religion is unchecked, Christianity is just as brutal and cruel as Islam and Hinduism are. Judaism probably would be, too, since it preaches the same repressive tenants.
Liberté. Égalité. Fraternité.
Even if Islam didn't exist, you would expect the Middle East to be a violent place.
If you notice something good in yourself, give credit to God, not to yourself, but be certain the evil you commit is always your own and yours to acknowledge.
Since 1 in 5 people on this planet affiliate themselves with it, I'm gonna say it's obvious, yeah it's peaceful.
Unfortunately you've got people who've wanted to use Islam as an excuse to further their own worldly ambitions. You've got people who have plenty of access to guns but little access to knowledge.
I can go on a Hare Krishna inspired killing rampage, does that make those delightful people selling pencils at the airport violent? Does it make Hare violent? Or is it me using old Hare as a justifier?
Religion is a man-made and man-run government sitting on top of spiritual ideas, ideas about our place in the universe, and the ideas of what society should be. And different leaders can take the same root ideas to interpret and preach them to others in very different ways while continuing to claim the same umbrella name like "Christianity" or "Islam". Sometimes these different teachings are broken out into formally recognized denominations, sometimes not.
So the most practical answer is that Islam as an umbrella label for religious practices is nether peaceful nor violent in itself, because it's individual interpretations and practices that make it peaceful or violent.
Those who would call Islam inherently violent and Christianity inherently peaceful are going a long way to overlooking all the violence the Bible can be interpreted to allow or even encourage, as evidenced by its warping in the past to justify great amounts of violence from the Crusades to the Salem Witch Trials.
